general problems of the 2014 GMC Sierra 2500

Gm refuses to repair the defective finish on my truck, their claim is that it only applies to trucks covered under the 3 year -36k warranty. This is a manufacturing defect that they admit to in the attached TSB. There should be a recall mandated for this. We spent a ton of hard earned money on these trucks.

I purchased this truck November 26 2016, within a month I was sitiing in my driveway I turned the truck on when I went out to go to work in the morning I got a bunch of flashing lights service stabilitrak, service 4wheel drive, service traction control, made multiple attempts to contact five star auto in biddeford, brought the truck in they refused to fix issues, asked for a trade nothing on the lot was worth purchasing without putting me out more than I already owed,christmas morning the truck was towed to weirs in arundel they pulled the truck apart and found a bunch of wires were corroded and the frame of the truck was caked with rocks mud and sand which had caused the corrosion, they fixed the issue. Within a couple months the same issue came back up and once again the truck was in the shop getting worked on. The problem is not fixed after spending money to fix a problem I had less than 30 days from buying this vehicle(driving completely normal will cause these lights to flash at random times) , all the lights do still come on randomly and today while at the dayton country store my transmission in my truck went, I am waiting to get my truck towed from the store to a shop! for a vehicle that the carfax came back clean and the dealership made no attempt in helping me fix or pay for any issues I have had. Im now struggling with a vehicle that I was lied to about the condition it was in after paying $32,000 for a truck. I have kept all documentation and have images that were sent to me from weirs.
